PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 529,308, dated November 13, 1894.

Application filed March 21, 1894. Serial No. 504,548- (No model.)

,To all whom it may concern.-

Be it known that I, EDWARD E. PINKERTON, of Sioux City, in the county of Woodbury and State of Iowa, have invented a new and Improved Paper Box, of which the following is a full, clear, and exact description.

My invention is an improvement in that class of folding or knock-down boxes which are formed from a single integral blank; and the construction of the same is as hereinafter set forth.

Reference is to be had to the accompanying drawings, formingapart of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a perspective view of the improvement, showing the box complete; and Fig. 2 is an enlarged face view of the blank from which the box is made.

The improved knockdown box is made from a single piece of cardboard or other suitable material and is formed of a blank, shown in Fig. 2, the blank comprising the sides A, B, B and O, O, the several parts being divided one from the other by creases E, E, E E as plainly shown in said Fig. 2. The side A is formed with the head pieces A, A each having curved sides and of which the head piece A is formed with the cut'in flaps A and A while similar cut-in flaps A A are formed in the head piece A The flaps A A leave a central portion A and a like central portion A is formed between the flaps A A of the other head pieceA The sides B and B are formed with rectangular head pieces B B and B B respectively, provided with the angular slots 13, B B B respectively. Shown in Fig. 2.

The fourth side of the box is formed by the two blank ends 0 0 adapted to overlap as plainly indicated in Fig. 1, each of the said sides or blank ends being provided with the head pieces 0 O and O C respectively. In the head pieces 0 G are formed the struck up tongues O O and similar tongues C C are formed in the head pieces 0 respectively. .The inner edges of the said head pieces are cut out as plainly shown in Fig. 2, so as to permit of conveniently passing into the interlocking, other head pieces as hereinafter more fully described.

The head pieces C B A, B and O are divided from their respective sides 0, B, A, B, O, by a longitudinally-extending crease F and a like crease F separates the said sides from the head pieces 0 B A B 0 When the blank has been made in this manner and it is desired to set up the box, then the oper ator turns the sides B, B at right angles to the side A and then overlaps the ends C, C to form the fourth side of the box opposite the side A. The operator then closes one end of the box by moving the head pieces B and B at right angles to their sides, that is, inwardly toward each other, so as to overlap, and then swings the head pieces 0 G downward over the end pieces B B and then the head piece A is swung upward to pass over the lower ends of the head pieces 0 C after which the tongue A is passed into the slot B and the other tongue A is passed into the slot B The tongue 0 is bent outward so as to form a resting place for the edge of the end piece 0 and the tongue 0 of the end piece 0 is bent inward so as to form an abutment for the inner edge of the head piece 0 The central portions A and A of the head pieces A and A firmly abut against the outer faces of the head pieces 0 O so that all the parts are securely locked in place on this end of the box. The operator then closes the other end in the same manner as described above, relative to the head pieces A B B C 0 that is, the head pieces B B are moved inward at right angles to their sides B B after which the head pieces C C are swung downward to engage with their tongues 0 C the corresponding edges of the head pieces 0 C respectively, after which the head piece A is swung upward and its tongues A A are engaged with the slots B B so as to completely close this end of the box. The box is then filled from the top and the half covers 0 C turned down to completely close the box.

It will be seen that a box of this description can be readily cut or stamped or otherwise formed from a single sheet of material such as pasteboard, and readily creased and folded, and the individual parts securely locked in place, as above described, to hold the contents of the box in position.

Having thus fully described my invention,

ICO

I claim as new and desire to secure by Letters Patent- 1. A folding-box blank formed, integrally, of the center or bottom piece having folding 5 heads provided with lateral locking tongues, two side pieces having heads provided with slots to receive said tongues, and two end portions having head pieces with tongues on their inner sides, which, when the blank is IO folded, project laterally and thus engage with the aforesaid locking tongues, as shown and described.

2. Anirnproved knock-down box made from a single blank having a central portion, two side portions, and end or outer side portions, all arranged parallel and having folding ends or heads, the central heads and adjacent side heads interlocking, and the heads of the exterior portions or sides having projections that lock with the other engaging parts of the central and inner side heads, when the blank is folded, as shown and described.
